Quality Control

Our production of this polymeric resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen blanket) to preserve product integrity. Keep away from heat sources and open flame.
